Alloy 7050
aluminum plate sheet is a zinc-magnesium-copper type aluminium alloy for US navy
and Air force to provide a high-strength materials resistant to
stress-corrosion, primarily for thick-section applications. In addition to its
high stress-corrosion resistance, it can be heat-treated and mechanically worked
to give a higher toughness at a given strength level than most other 7*** series
aluminium alloys.
Alloy 7050
aluminum plate sheet is unusual in two respects: it contains zirconium(in place
of chromium) to control recrystallization and grain size, and it has a Cu/Mg
ratio greater than 0.8. The absence of chromium contributes to the low
quench-sensitivity of 7050, and the relatively high copper content results in
additional strengthening during second-step aging.
Alloy 7050
aluminum plate sheet is the principal choice for aerospace applications,
especially in the 3-6 inch thickness range. It exhibits better
toughness/corrosion resistance characteristics than the older, more established
alloy 7075. Since it is less quench sensitive than most other aerospace alloys,
this alloy maintains its strength properties in thicker sections while retaining
good stress corrosion cracking resistance and fracture toughness levels. AMS
4050 is commonly associated with 7050, though various manufacturers require
their own specifications.
